Question

1. Out of the three rays (I, J, H) shown in the diagram, which ray will suffer Total Internal Reflection while inside the prism? (Critical angle of the prism is 42°.)
2. Copy the diagram to complete the path of the ray which you have named in (a) till it comes out of the prism.

Answer 1

1. J is the ray that would experience complete internal reflection while within the prism, out of the three, since its angle of incidence is larger than the critical angle.
2.
